Is there a way to configure sqlplus to output errors to STDERR instead of STDOUT?
I'd like to quote Manoj here:
File descriptor 1 is the standard output (stdout
).
File descriptor 2 is the standard error (stderr
).
Here is one way to remember this construct (although it is not entirely accurate): at first, 2>1
may look like a good way to redirect stderr to stdout. However, it will actually be interpreted as "redirect stderr to a file named 1". &
indicates that what follows and precedes is a file descriptor and not a filename. So the construct becomes: 2>&1
.
Consider >& as redirect merger operator.
Referring link to the source: In the shell, what does " 2>&1 " mean?
